Patent attributes
A vehicle-mounted display apparatus includes a display panel, a geographic position acquisition circuit, a processor, and a display panel driving circuit. The geographic position acquisition circuit acquires a current geographic position of a vehicle. The processor determines whether the current geographic position of the vehicle is within a stored geographic range, and if so, generates a first control signal. The display panel driving circuit controls the display panel to display the vehicle information upon receiving the first control signal from the processor. The vehicle information includes at least one of vehicle license information and a pseudo mobile phone number. In the display apparatus, an information push terminal communicating circuit communicates with an information push terminal to obtain the vehicle information and the stored geographic range, and a server communicating circuit communicates with a server to obtain the pseudo mobile phone number corresponding to an identification for the display apparatus.
